This week's MNF feature on ESPN takes a look at the biggest problem with the San Diego Chargers -- not the coach, not the offense, but one specific injury on defense. But looking back, it's surprising how little impact similar injuries had on other teams.

Losing Mr. Williams is a big deal, but it was really a trio of injuries. Ian Scott, Travis Johnson and Ryon Bingham all went down either in the preseason or after game 1, so there has been no backup. Or rather, the nose has been manned alternately by a cast-off from a bad 4-3 team, a larger-than-average rental-car clerk and a guy who hasn't played American Football since high school.
